This invention relates to improvements in picture frames, the rods and other elements of which may be mounted and dismounted at will, providing a very practical and easy 5 system of assembling the frame.

It is well known that the average person, who does not possess more than the minimum of manual ability, experiences some diiiiculty if he desires to make a picture frame, inasmuch as the ordinary wooden frames are beyond the reach of the majority, and the gummed tapes or ribbons to make the framed glasses, so much in vogue at the present time, also always require a certain amount of ability, even though the advertisements may state the contrary, because on moistening themv to adhere to the border of the glass and cardboard, the twisting of the tape occurs, an

- inconvenience which cannot always be overcome, and this necessitates moistening another piece. Moreover, no matter how well the tape may be adhered, the dampness will withtime disjoin it, and the frame will have to be made anew. A s f The present improvements obviate all these inconveniences, inasmuch las they refer to rods, preferably metallic,-which lanyone can cut with simple scissors and assemble, withoutl requiring great ability or experience as 30. regards exactitude, the adjusting corners being suii'icient to conceal anyilack of exactitude.

In order that my invention may be clearly comprehensible, I have illustrated same with various figures, wherein:

Fig. 1 is a front view of a rod;

Fig. 2 is a Vfront view of the back part of a corner member; Fig. 2a is a side view thereof.

Fig. 3 is a front and side `View of the suspension ring; f

Fig. 4 is a side view of the suspension ring inserted and doubled for the desired inclination; 4 j s 451 j Fig. 5 is a frontfview' of a detail'of a corner;

466,982, and in Argentina May 5, 1930.

Oonstmction These improvements comprisethree essential parts; the firsta rod a, (Fig. l), the second an adjusting corner b, (Fig. 5), and the third the suspension ring c, (Figs. 3 and 4).

Therod a (Fig. l), is made of sheet metal and doubled in the manner shown in Fig. 1, so that the curve which its fold produces will receive the glass, figure, and cardboard back usual to4 every picture. These rods a can be manufactured in every size and length in order that they may be sold by any measure, in addition tothe ease with which they may becut at any desired point by the person using them. j

The second part is the adjusting corner b (Fig. 5'), made from a sheet of the same material as the rod a in the following manner: The front of the adjusting corner b (Fig. 5), maybe of triangular or any other convenient form, with wing Lmembers b1 doubled backwards in order that their points will'form a right angle, the wing members remaining in thefforrn shown in Fig.-2.' These wings b1 have a small groove d or inclination, or moulding, or any suitable embossment, and inlsaid groove a number of perfor-ations e areY made in such manner that they form an interior projection. By the use of the word projection in connection with the perforations e, it is meant to indicate the small rough projections which remain on one side of a sheet of metal in which perforations have been made, a typical case in point being that of a grater.

The third part of these improvements is constituted/'by a suspension ring c (Figs. 3 and 4). It comprises a common ring c, which is held by a clasp c1, the latter enclosing the ringo .atits upper part, and is made in such a manner that it forms two sections, one longer than the other (Fig. 3).

The material employed in the execution 'of the parts described will preferably be metal, although celluloid, galalith, and any other material adaptable to the object in view, may be employed. In the sanne Inanner, both the rods a and adjusting corners b will not only be plain as shown in the attached drawings, but may also bear every class of stamping of high or bass relief, including mouldings, etc., of any type, and'may be of any colour, .toneand system of ornamentation, graphic decoration and embellish-V ment which may be desired, and may be of all sizes, without this meaning adeparture from the sphere of the present invention.

Assembly of the frame The principal characteristic of the present improvements is the ease with which the frame is made and assembled, even by persons completely lacking inmanual ability.

Previously the glass o will have been cut to size, as also the picture or figure which it is desired to frame, the details of which are shown in'Fig. 5 indicated with the letter f,

ligure the clasp c1 .is shown having. penetrated in the cardboard r and doubled in an upward direction, and its shorter length forms an inclined angle, as has been stated.

Y On this cardboard back r is. placed the picture fr generally Yof cardboard or -pasteboard, and on thepicture f the glass fo. The

conjunctv having been obtained, two lengths of the rod are cut, t-helonger. a, Fig. 6,*being the vertical rods, and the conjunct -is made to enterfinto same, the fold al-of the rods being calculatedto eect a slight pressure.- JThe horizontal. rods .:(F ig. 6) are then out and are placed thesame as the vertical ones, lit being found better to always cut them a little less, as indicated in Fig. 6. The four rods a, having been ,placed iny position, itis necessary to secure them together, which is done by means of the adjusting corners b. The

` ing of-fthe frame Ais not possible, unle-ss the groove d of these ycor-'ners1(Fig.2) bears some perforations e with projections, which hold the fold ,al ofthe rods a', and with this end in view the width of said fold a1 and the position ofthe perforations e (Fig. 2) have been calculated. Oncethe four adjusting corners have been, placedin position, the dismountf.

avoid their biting the projections of the per'- forations e and withdrawing them from their position.

Having thus described'my invention, what I claim asnew, and desire to secure by Letters Patent, is:

In a picture` frame including its long and short channel bar-s forming the frame for the reception of glass, picture and cardboard backing, corner pieces to hold the channel bars together, each bf said corner pieces comprising a substantially triangularly shaped body, triangular wing members formed with two sides of said body and bent upon the same and l having grooves formed therein, tongues formed in the bottoni ofthe grooves by perforating the material thereof, and adapted to engage Ythe channels of the frame bars.

In testimony whereof, I ailiXmy signature.
